What's really 'annoying' is the fact that the info stored on the mag. strip of your credit card can be scanned anywhere anytime w/o you even knowing it. Evidently that's happened to me twice now...but, it won't happen again. I carry my cards in a metal 'wallet' these days.
(You haven't really lived until your phone rings, you pick it up, and a guy on the other end says, "Mr. [Jones], I'm John Smith with Last Chance National Bank's Master Card fraud division...how are you today, sir?" Well, up 'til THAT point I'd been just fine...)
